What term best matches the creation of the Judicial Branch as described in the text?

The Judiciary Act of 1789 is the term that best matches the creation of the Judicial Branch. This act was crucial in establishing the federal court system in the United States, defining the structure and jurisdiction of the federal judiciary. It set up the Supreme Court, along with lower federal courts, and outlined the role of the judiciary in the framework of government established by the Constitution.

This legislation was significant because, although the Constitution provided for the establishment of a judicial system, it did not itself create the specific structure. The Judiciary Act filled in those gaps, allowing for the implementation of the judiciary as an essential coequal branch of government alongside the legislative and executive branches.

Other options, such as the Constitutional Convention, relate to the creation of the Constitution itself, while the Bill of Rights pertains to the protection of individual liberties. The Emancipation Proclamation, on the other hand, primarily involved the issue of slavery and did not directly contribute to the judicial framework. Therefore, the Judiciary Act of 1789 directly aligns with the establishment of the Judicial Branch in the context provided.
